Monotonic and cyclic properties of LENS fabricated 4140 and AISI 4140 steel alloys were analyzed both experimentally and computationally. The LENS 4140 steel was fabricated using a Laser Engineered Net Shaping (LENS) manufacturing technique. Monotonic and cyclic behavior was modeled using an Internal State Variable (ISV) model. The model can simulate plasticity and damage processes at various temperatures and strain rates. The damage evolution is represented by void nucleation, growth and coalescence leading to ductile failure of the material. For low cycle fatigue, damage evolution is governed by the nucleation and growth of voids in front of a crack tip and related with the main crack leading to crack advance.
